So recently we have been hitting the low 50s and an occasional 45 to 48 at night and my coconut palm is showing severe yellowing with brown spots all over it. I'm not sure if it's a disease or the cool weather that is causing it ill show pics below of what it looked like in September vs now. The last pic it has yellow patches all over I have no idea why.
I thought some people here might be interested in some of the research that is done on palms , in my lab we are working with Cocos nucifera and are trying to develop different methods for ex-situ conservation such as in vitro culture, cryopreservation. And recently we developed a protocol which allows the micropropagation on the coconut palm. This allows us to safely store these palms in in vitro genebanks but also use the material for cryopreservation or to replant coconuts on the field. On the pictures you can see the multiple shoots which are all clones.
What is your opinion on using these techniques for safeguarding palms?

Out of all the coconut varieties in the world, which one would you say can handle cool temps for the longest?

A month ago I purchased a young coconut that had been grown in a grocery bag. It had terrible root wrap, and I had to sever its thicker roots, which had fused with the bag. It looked yellow and sick, but it’s putting out a new frond now. Do you think it’s going to grow out of the root-wrap stage? (I’m also including pics of my other palms, which came with the house.)
So a little over two years ago I was on Maui and was able to get a sprouted coconut (about 2 inches) back to my home in Montana. Last spring it grew large enough to hit my ceiling. I had a large LED grow light over it but once it grew large enough, it just shot fronds past it. Admitting it was likely the end, I put it outside during the summer. It survived, despite some of the fronds dried out from Montana's very dry climate near the mountains. However, its growth greatly slowed and I was able to bring it back in during the fall. Well, as summer approaches, the coconut palm is still alive. So basically, how long can I slow its growth without killing it?
